This is set as the same as the manga so all of the character are still there if you want to play them or you can make up your own character k. ui'm going to be RPing as the Millennium Earl and Akumas and below is a discription of it and go on to Wiki for more information and if there is anything more to information that is needed to know i will post in ok~

Exorcists are specially chosen humans who are gifted with the ability to control and use Innocence, a divine substance created in ages past to combat the Earl and his minions. According to the Order's history, 109 fragments of Innocence were scattered around the world at the end of The Great Flood. Once an Innocence fragment is found to be compatible to a particular user, it can become a weapon or tool for the user to wield in battle.

The Millennium Earl is aided in his plans by The Noah Clan, humans who are direct descendants of Noah himself. Each member of this clan is gifted with great power and each represents a different 'aspect' of Noah. They are identified by their gray skin and line of cross-shaped markings on their foreheads. As the story progresses, the members of the clan are revealed: Road Kamelot (The Dreams of Noah), Tyki Mikk (The Pleasures of Noah), Jasdero and Debitto - Jasdebi (The Bonds of Noah), Skin Boric (The Wrath of Noah), and Lulubell (The Lust of Noah).

The Earl commands an army of demonic creatures called Akuma to do his bidding. Akuma are created by taking advantage of someone's grief over the death of a loved one. The Earl tricks individuals into bringing their loved one back to life through a skeletal 'doll,' only to have that doll kill them and turn them into an Akuma with the soul of the dead loved one trapped inside. Akuma are able to evolve and with each new level gained, they grow more intelligent, powerful, and sadistic. Since Akuma can impersonate humans to blend in with people, exorcists are routinely assigned to track down and eliminate them. Allen is the only exorcist able to actually see past the Akuma's disguise. This is due to his 'cursed' left eye which grants him both the ability to 'sense' when an Akuma is nearby as well as see the imprisoned soul within the Akuma's body.
